Storage Cleanup

该 Skill 用 bash 脚本扫描并清理 macOS 与 Linux 上的磁盘占用项，包括垃圾箱、临时文件、各类开发缓存、旧内核、snap 修订、Homebrew、Docker 与 Xcode 产物。默认提供 dry-run 预览和 --yes 执行，可按类别跳过，并报告释放的空间；部分目标需用户手动处理。

description
One-command disk cleanup for macOS and Linux — trash, caches, temp files, old kernels, snap revisions, Homebrew, Docker, and Xcode artifacts. Use when user asks to free storage, clean up disk, reclaim space, reduce disk usage, or encounters low disk / "disk full" warnings. Safe by default with dry-run mode. No dependencies beyond bash and awk.

Storage Cleanup

Reclaim tens of gigabytes in one command. No config files, no dependencies, no damage.

Why This Skill

Systems accumulate junk silently — IDE caches, old snap revisions, stale pip builds, forgotten trash, outdated kernels. Manually hunting them down wastes time and risks deleting the wrong thing.

This skill:

  • Scans 12+ cleanup targets across both macOS and Linux in a single pass
  • Safe by default — --dry-run shows exactly what would be cleaned before touching anything
  • Zero dependencies — pure bash + awk, works on any stock macOS or Linux install
  • Cross-platform — auto-detects OS and runs only what applies (no errors on missing tools)
  • Selective — skip any category with --skip-kernels, --skip-docker, --skip-brew, --skip-snap
  • Reports savings — shows before/after disk usage and exact bytes freed

Quick Start

# Preview what would be cleaned (safe, changes nothing)
bash scripts/cleanup.sh --dry-run

# Clean everything
bash scripts/cleanup.sh --yes

# Clean but keep Docker and old kernels
bash scripts/cleanup.sh --yes --skip-docker --skip-kernels

What Gets Cleaned

Both Platforms

Target Typical Size Notes
Trash 1–50 GB macOS ~/.Trash, Linux ~/.local/share/Trash
Stale /tmp 1–10 GB pip/npm/rust build dirs older than 60 min
pip cache 50–500 MB pip cache purge
Go build cache 100 MB–2 GB go clean -cache
pnpm / yarn / node caches 50–500 MB Safe to regenerate
JetBrains IDE cache 1–10 GB IntelliJ, PyCharm, WebStorm, etc.
Whisper model cache 1–5 GB Redownloads on demand
Chrome / Firefox cache 200 MB–2 GB Browsing cache only
Playwright browsers 200 MB–1 GB Redownloads on demand
Docker dangling images 0–10 GB Only unreferenced images + build cache

Linux Only

Target Typical Size Notes
Apt cache 200 MB–2 GB apt clean
Journal logs 500 MB–4 GB Vacuumed to 200 MB
Disabled snap revisions 500 MB–5 GB Old versions kept by snapd
Old kernels 200–800 MB Keeps current running kernel

macOS Only

Target Typical Size Notes
Homebrew old versions 500 MB–5 GB brew cleanup --prune=7
Xcode DerivedData 2–30 GB Build artifacts, safe to clear
Xcode Archives 1–20 GB Old build archives
iOS DeviceSupport 2–15 GB Old device symbols
CoreSimulator caches 500 MB–5 GB Simulator disk images
Old user logs 100 MB–1 GB Logs older than 30 days

Options

Flag Effect
--dry-run Preview cleanup without deleting anything
--yes / -y Run without confirmation prompts
--skip-kernels Don't remove old kernels (Linux)
--skip-snap Don't remove disabled snap revisions (Linux)
--skip-docker Don't prune Docker
--skip-brew Don't clean Homebrew

Manual Extras

Targets the script doesn't touch (check manually if needed):

  • Ollama models: ollama list → ollama rm <unused>
  • npm global cache: npm cache clean --force
  • Conda envs: conda env list → conda remove -n <env> --all
  • Compressed logs: sudo find /var/log -name "*.gz" -delete
  • Flatpak (Linux): flatpak uninstall --unused
  • Time Machine snapshots (macOS): tmutil listlocalsnapshots / → tmutil deletelocalsnapshots <date>
